ABSTRACT:
A tubular member is adapted to communicate with an intake manifold and combustion gas conduit of a combustion engine. A housing of the valve has an interior space and a slidable valve member normally extends across and blocks the interior of the tubular member, having a portion extending into the interior space of the housing. At least one flexible diaphragm subdivides the interior space into two chambers and is fixed to the portion of the valve member. One of the chambers communicates with the atmosphere. A first and a second conduit connect the other chamber with the manifold and with the atmosphere, respectively. An electromagnetic valve is operative for alternately connecting the other chamber with the first and with the second conduit, respectively.
